Can you connect two DPP twins together to get a total of 3 satellites? I don't have any extra dishpro duals laying around, but I have a couple of DPP Twins. My guess is no, but I thought I'd ask.
But if I had a couple of extra's, I would try it and see, and then maybe use it in an emergency on a personal installation.
EDIT: And I'm sure you already knew this, but you could connect two DPP Twin LNBF through a DP-34. But I just realized that you would either need 2 receivers, or add the DPP-44 Power Inserter to the DP-34.
Yeah, I was just wanting to find a way to connect the output from the second DPP Twin to the input on the other DPP Twin in order to get 3 satellite locations. I figured that it wasn't possible. This is really just because I'm going to go HD on my tailgate setup and wanted to be on the lookout for some spare parts if I needed.
